Abstract
The utility model relates to a novel boiler which is a saturated steam heating device comprising a high-temperature reheater, a low-temperature reheater, a desuperheater and a regulating valve; a steam pocket is connected with an inlet pipe of the high-temperature reheater or an inlet pipe of the low-temperature reheater by a steam guide pipe or the regulating valve; a saturated steam pipe is connected with the inlet pipe of the low-temperature reheater, and an outlet pipe of the low-temperature reheater is connected with the inlet pipe of the high-temperature reheater by the desuperheater; and an outlet pipe of the high-temperature reheater is connected with a main reheating steam pipe. The saturated steam heating device leads saturated steam to be heated into superheated steam, thus improving the work applying capability of steam, obtaining high economic benefit by less heat consumption, and having the effect of half the work with double results.
Description
Technical field
The invention belongs to the recovery of heat energy and utilize technical field, the particularly technical field of energy recovery and utilization in the industrial production.
Background technology
Energy-conservation is long-range strategy and policy of China's economy and social development, also is to work as very urgent task of last item; At present industries such as iron and steel, cement, phosphorous chemical industry utilize waste heat to produce saturated vapor to be used for generating efficiency low, the heat supply conveying capacity is poor, now how improving the saturated vapor utilization ratio is a problem that urgency is to be solved, also is a major issue of benefiting the nation and the people.
Summary of the invention
The purpose of this patent invention is by making or transform boiler, increase external saturated vapor reheater in steam generator system, external saturated vapor being heated to be superheated steam; Increased steam connection tube and the control valve of drum to reheater, make boiler guarantee that when not having external saturated vapor the saturated vapor in the part drum directly enters reheater, prevent that the reheater overtemperature from damaging, make boiler energy operate as normal when not having external saturated vapor; Superheater and reheater are independent each other in the steam generator system, separately the superheated steam pressure and temperature of being independent of each other during work, and reheated steam after the heating and superheated steam remove Turbo-generator Set power generation and heat supply separately; The principle of design improvement heating saturated vapor is: when the total heating efficiency of boiler was no more than rated load, can self-produced superheated steam can heat external saturated vapor again was superheated steam; Saturated vapor becomes superheated steam and is greatly improved to the Turbo-generator Set mechanical efficiency, and the steam heating ability has also obtained enhancing, and heat energy utilization is more reasonable, and production run is safety and stability more, and has good social benefit and economic benefit.
This saturated vapor heating boiler scheme of dealing with problems again is: a kind of New-type boiler is characterized in that the saturated vapor heater that comprises that high temperature reheater, low-temperature reheater, attemperator, control valve are formed; Drum is connected with the high temperature reheater inlet tube with control valve by steam guiding tube or the low-temperature reheater inlet connects, saturated steam pipe is connected with the low-temperature reheater inlet tube, the low-temperature reheater outlet is connected with the high temperature reheater inlet tube by attemperator, and the high temperature reheater outlet is connected with hot main steam pipe again; Drum is connected with the low temperature superheater inlet tube by steam guiding tube, and the low temperature superheater outlet is connected with the high temperature superheater inlet tube by cooler, and the high temperature superheater outlet is connected with overheated main steam pipe; Drum is connected with furnace body top steam pipe by steam pipe, and drum is connected with furnace body bottom feed pipe by feed pipe.
The beneficial effects of the utility model are, except that self-produced steam own, can also be heated into high-quality superheated steam to inferior saturated vapor, improved the acting ability of steam, bring very high economic benefit with seldom heat exhaustion, played the effect of getting twice the result with half the effort, promptly save fuel source, reduced production cost, improved economic benefit again.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, drum, 2, steam guiding tube, 3, control valve, 4, steam pipe, 5, attemperator, 6, high temperature superheater, 7, low temperature superheater, 8, high temperature reheater, 9, low-temperature reheater, 10, flue, 11, cooler, 12, hot main steam pipe again, 13, saturated steam pipe, 14, overheated main steam pipe, 15, furnace body, 16, feed pipe.
The specific embodiment
A kind of New-type boiler specific implementation method is that high temperature superheater 6, low temperature superheater 7, high temperature reheater 8, low-temperature reheater 9 are arranged in furnace body 15 stove one's parents portions and the flue 10; Drum 1 is connected with high temperature reheater 8 inlet tubes with control valve 3 by steam guiding tube 2; Saturated steam pipe 13 is connected with low-temperature reheater 9 inlet tubes, and low-temperature reheater 9 outlets are connected with high temperature reheater 8 inlet tubes by attemperator 5, and high temperature reheater 8 outlets are connected with hot main steam pipe 12 again; Drum 1 is connected with low temperature superheater 7 inlet tubes by steam guiding tube 2, and low temperature superheater 7 outlets are connected with high temperature superheater 6 inlet tubes by cooler 11, and high temperature superheater 6 outlets are connected with overheated main steam pipe 14; Drum 1 is connected with furnace body 15 top steam outlet pipes by steam pipe, and drum 1 is connected with furnace body 15 bottom feed pipes by feed pipe 16.
Using method
At first to give the boiler topped up with water, and keep drum 1 water level in the center by feed pipe 16; Fuel is in furnace body 15 internal combustion, body 15 produces steam and enters drum 1 by steam pipe 4, steam enters heating in the low temperature superheater 7 by steam guiding tube 2 in the drum 1, steam after the heating enters high temperature superheater 6 by cooler 11 and heats, and the qualified superheated steam after the heating is sent utilization by hot main steam pipe 14; Saturated vapor enters low-temperature reheater 9 by saturated steam pipe 13 and heats, and the steam after the heating enters attemperator 4 and enters high temperature reheater 8 and heat, and the qualified superheated steam after the heating is sent utilization by hot main steam pipe 12 again; When having external saturated vapor to heat,, the control valves in the middle of drum 1 and the high temperature reheater 8 are not opened, the fractional saturation steam in the drum 1 is delivered in the high temperature reheater 8, prevent that high temperature reheater 8 overtemperatures from damaging for can make normal operation of boiler.
